阀门开关及其管道系统
摘要：
本申请公开了一种阀门开关及其管道系统。所述阀门开关包括：第一蜗轮(201)；与第一蜗轮(201)相连接的第一蜗杆(203)；以及与第一蜗杆(203)相连接的第一主轴(204)，其中，所述第一蜗轮(201)包括轴孔，用于与阀轴连接，所述第一主轴(204)具有第一轴头(205)，用于与操作装置连接；所述操作装置包括：手柄(301)；与手柄相联接的第二主轴(302)以及与第二主轴(302)相联接的第一轴孔(303)。其中，所述阀门开关用于将操作装置绕第一轴向的转动转变为所述第一蜗轮绕第二轴向的转动，并且将操作装置的第一转速减小为所述第一蜗轮的第二转速。该阀门开关利用操作装置开合阀门，安装维修时由于不需要操作装置而节省了空间，较为方便。
摘要（英）：

The invention discloses a valve switch and a pipeline system thereof. The valve switch comprises a first worm wheel (201), a first worm (203) connected with the first worm wheel (201) and a first main shaft (204) connected with the first worm (203), wherein the first worm wheel (201) comprises a shaft hole used for being connected with a valve shaft, and the first main shaft (204) is provided with a first shaft head (205) used for being connected with an operation device; and the operation device comprises a handle (301), a second main shaft (302) connected with the handle, and a first shaft hole (303) connected with the second main shaft (302). The valve switch is used for converting rotation of the operation device in the first axial direction into rotation of the first worm wheel in the second axial direction, and reducing the first rotation speed of the operation device into the second rotation speed of the first worm wheel. The valve switch opens and closes a valve through the operation device, the operation device is not needed during installation and maintenance so that the space can be saved, and convenience is brought.
